I’m studying an article on wind turbines. The article says that for electricity generation, a wind turbine rotating at high speed providing a low torque is preferable to a turbine rotating at a low speed and producing a high torque. Can anyone explain why this is the case? Surely the speed could be altered easily using a sequence of gears before the generator?

I’m gonna add onto the above answer. Wind turbines operate at a high speed with low torque because it will garner the most efficiency. When the wind turbine operates at a "light breeze", the blades will meet less friction and can therefore use that towards power generation instead.

It would allow the blades to turn in a gentle breeze
